Partitioning locomotor energy use among and within muscles. Muscle blood flow as a measure of muscle oxygen consumptionRichard L Marsh
Department of Biology, Northeastern University, 360 Huntington Avenue, Boston, MA 02115, USA
J Exp Biol 209:2385-94. 2006..The practical considerations of using the injectable microsphere technique to measure muscle blood flow in this context are discussed...
The energetic costs of trunk and distal-limb loading during walking and running in guinea fowl Numida meleagris: I. Organismal metabolism and biomechanicsRichard L Marsh
Department of Biology, Northeastern University, 360 Huntington Avenue, Boston, MA 02115, USA
J Exp Biol 209:2050-63. 2006..Thus, the increased energy demand of distal limb loading in guinea fowl is predicted to cause increases in energy use by both stance- and swing-phase muscles...
Partitioning the energetics of walking and running: swinging the limbs is expensiveRichard L Marsh
Department of Biology, Northeastern University, 360 Huntington Avenue, Boston, MA 02115, USA
Science 303:80-3. 2004..Models integrating the energetics and mechanics of running will benefit from more detailed information on the distribution of energy use by the muscles...
The energetic costs of trunk and distal-limb loading during walking and running in guinea fowl Numida meleagris: II. Muscle energy use as indicated by blood flowDavid J Ellerby
Department of Biology, Northeastern University, 360 Huntington Avenue, Boston, MA 02115, USA
J Exp Biol 209:2064-75. 2006....
Blood flow in guinea fowl Numida meleagris as an indicator of energy expenditure by individual muscles during walking and runningDavid J Ellerby
Department of Biology, Northeastern University, 360 Huntington Avenue, Boston, MA 02115, USA
J Physiol 564:631-48. 2005..Our data provide a basis for evaluating hypotheses relating the mechanics and energetics of legged locomotion...
Performance of guinea fowl Numida meleagris during jumping requires storage and release of elastic energyHavalee T Henry
Department of Biology, Northeastern University, Boston, MA 02115, USA
J Exp Biol 208:3293-302. 2005..To account for high power outputs, we concluded that energy has to be stored early in the jumps and released later during peak power production, presumably using mechanisms similar to those found in more specialized jumpers...
Effects of exercise on the biomechanical, biochemical and structural properties of tendonsCindy I Buchanan
PT Department, 6RB, Northeastern University, 360 Huntington Ave, Boston, MA 02115, USA
Comp Biochem Physiol A Mol Integr Physiol 133:1101-7. 2002..The lack of integrative studies makes it difficult to definitively associate changes in the mechanical properties of tendon with chemical composition and structure...
Measurement of maximum oxygen consumption in Guinea fowl Numida meleagris indicates that birds and mammals display a similar diversity of aerobic scopes during runningDavid J Ellerby
Department of Biology, Northeastern University, Boston, MA, 02115, USA
Physiol Biochem Zool 76:695-703. 2003..These data confirm a previous prediction that birds have a diversity of factorial aerobic scopes similar to that exhibited by mammals...
Probing the limits to muscle-powered accelerations: lessons from jumping bullfrogsThomas J Roberts
Biology Department, Northeastern University, 414 Mugar, 360 Huntington Ave, Boston, MA 02115, USA
J Exp Biol 206:2567-80. 2003..These results can explain the high power outputs observed in jumping frogs. More generally, our model suggests how the function of non-muscular elements of the musculoskeletal system enhances performance in muscle-powered accelerations...

Muscle designed for maximum short-term power output: quail flight muscleGraham N Askew
School of Biology, University of Leeds, Leeds LS2 9JT, UK
J Exp Biol 205:2153-60. 2002..These considerations serve as a reminder that the maximum power-producing capacities of muscles need to be considered in the context of the in vivo situation within which the muscles operate...
